What to do about this girl at work who has been saying bad things about me?

Sounds like she could be what’s called a “toxic” person. A gossiper, pot stirrer. I’d say tame your own tongue and emotions then rise above it all. Let her make all her own messes and stay out of em. You will be the victor.

I think that seeking any kind of revenge on her would be going ‘too far’. If someone at work is making your work environment absolutely unbearable, then that’s probably something you should take up with your boss, manager, or any person that is in a higher position who can look at this situation and put a stop to it. Aside from that, the mature and smart thing to do would be to walk away and not take any part in it. Jumping in, confronting her, or doing anything to her electronic devices will only cause more trouble for you in the end.

I would say that you should contact your boss or manager or whoever and rise above it. Youre going there to work, not to hear lies being spread about yourself. S first you should try to stop it by fair means. Dont stoop down to her level though, maybe you should first find out what she says. Then you should just ask her about it politely. Even if she screams or anything, be polite to her ( i SWEAR! When you find someone being polite to you even when ur screaming or swearing your head off at them is the most embarassing thing ever. This will make her shut up herself) if you think that the whole thing is just silly and you arent going anywhere by asking her, as i said, just talk to your boss. Dont do anything like key logging her electronic devices because then it will be a big mess. Best thing to do is either ignore the whole thing, talk to your boss about it, or talk to her about it.

Kill her with kindness. In the end you will win and she will probably get fired. You will look good for keepin your head on with the drama she dished out
